The epic fifth series of fantasy drama Merlin continues on BBC One this weekend and darkness steals into the very heart of Camelot, as Morgana and her puppet Queen hatch a sinister plan to murder the King. As the plot thickens and reaches its deadly climax, can a suspicious Merlin unravel the truth before it’s too late?

‘A Lesson in Vengeance’ airs at 8pm on Saturday 17 November on BBC One. To whet your appetite, here are ten teasing lines of dialogue from the episode…

» ‘I have no name. There’s no name to give.’

» ‘Trust me, Arthur’s safe just as long as he remains in Camelot.’

» ‘These are uncommon things. Hard to come by, hard to prepare.’

» ‘When the time comes, and it will surely come soon, we need to be prepared.’

» ‘No, if it means me dying instead of her then so be it. I’d rather die.’

» ‘I’m going to do everything in my power to forget that you ever just said that.’

» ‘Should have done that years ago!’

» ‘I suppose experience should have taught me that by now.’

» ‘No one can deny your wisdom, you compassion and your loyalty.’

» ‘Well, at least it’s not the turnip stew!’
